HENRY O. HERRMANN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO \VARREN VEBSTER, OF SAME PLACE.

VENTILATOR AND CHIMNEY-TOP.

PECIPICATION forming part of Letters Patent No. 339,099, dated March 30, 1886.

Application filed October 21, 1885. Serial No. 180,513.

To aZZ whom it may concern.-

Be it known that I, HENRY O. HERB-MANN, a subject of the Emperor of Germany, residing in the city and county of Philadelphia,

5 State of Pennsylvania, have invented a new and useful Improvement in Ventilators and Chimney-Tops, which improvement is fully set forth in the following specification and accompanying drawings, in which m Figure 1 represents a side elevation of a ventilator and chimney -top embodying my invention. Fig. 2 represents a central vertical section thereof. Fig. 3 represents a section in line aa", Fig. 2. Fig. 4 represents a I 5 vertical section of a modification thereof.

Similar letters of reference indicate 'corresponding parts in the several figures.

My invention consists of a ventilator and chimneytop constructed substantially as hereinafter set forth, whereby an apartment may be readily ventilated and an unobstructed draft created in a chimney or flue, to which in either case the device is applied.

Referring to the drawings, A represents a tube or flue, to the upper part of which is secured. a-conical deflector, B, in such a mannor that no opening exists between the tube and the deflector. Sustained at the top of the tube, and elevated above the deflector B,

0 is a conical deflector, G, and above the same is supported a conical cap, 1), it being noticed that spaces exist between the cap D and the deflector C and between the deflector G and deflector B.

E represents a cylindrical tubular band, which is secured to the top of the tube A or either of the deflectors or the cap D and encircles said deflectors and caps, the band being of greater diameter than either of the said parts, so as to leave a space between the same.

The conical deflector G is of less diameter than the deflector B, and the cap D is of greater diameter than the deflector B. The

. encircling tube E is of greater diameter than 4 5 the said deflectors B O and cap D.

It will be seen that when the wind strikes the band E, should it pass over the top edge thereof and enter said band, it may strike the deflector C or deflector B, and is thus direct- (No model.)

ed upwardly, creating a vacuum in the tube A, and prevented from being blown into the same. Should the wind pass under the lower edge of the band or strike the deflector B, the same result is occasioned, and thus the ventilation of the room or apartment is reliably effected or a powerful and unobstructed draft is created in the chimney or flue, to which in either case the device is attached. The deflector G acts as a guard for preventing the wind admitted under the cap D from being directed into the tube, while the wind which strikes the deflector B is directed by the defiector C upwardly, just over the top of the tube, thus creating a powerful draft in the latter. Should the wind strike the cap D from above, it may descend around the outer edges of the deflectors G B, and create a downward draft between the cap and the deflectors, the tendency of which is to create an upward draft in the tube or flue A.

In order to prevent the lateral deflection of the wind as it strikes the deflector B, the latter is corrugated, forming a series of channels or pockets, which serve to catch the wind and direct it unfailingly upward above the top of 7 5 the tube A.

In Fig. at the deflector C is shown as a flat annulus and employed with the deflector B, the corrugations of the latter being omitted.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A ventilator and chimneytop having the corrugated deflector B, secured to the outer surface of the pipe A, at the top thereof, the 8 5 conical cap D, the tubular band E, and the intermediate deflector, 0, all of said parts being arranged and combined substantially as described.

2. A lower deflector secured to the top of the pipe, in combination with an upper defiector, a conical cap, and a tubular band surrounding the upper deflector and the rim of the base of the said cap, said parts being ar' ranged and combined substantially as and for 5 the purpose set forth.

3. A chimney-cowl having a bottom deflector, B, secured to the top of pipe A, an intermediate-deflector, G, and a conical top cap, as described, the conical cap D, the inclined 10 D, the diameter of the base of the top cap bedeflector G, and cylindrical tubular band E, ing greater than that of either of the said dei encircling said deflector O and of greater diflectors, and a cylindrical tubular band, E, I ameter than the base of the deflector B, subsurrounding said deflector C and the base of l stantially as and for the purpose set forth.

said top cap, D, substantially as and for the I H. O. HERRMANN.

purpose set forth. \Vitnesses:
